In an experimental timeframe of about ten years, (interactive) media installations and performances have established its recognition as new art form in public space. Artworks discover the interconnectedness of public space, interaction and new media. URBAN SCREENS investigates how the growing infrastructure of dynamic digital displays in urban space currently dominated by commercial forces can be utilized in this context and broadened with cultural content. The research project wants to network and sensitize engaged parties for possibilities to using the digital infrastructure for contributing to a lively urban society. The integration of current information technologies support the development of a new digital layer of the city in a merge of material and immaterial space redefining the function of this growing infrastructure. Interactivity and participation will bind the screens more to the communal context of the space and therefore create local identity and engagement.
